And at t equals zero the value of this graph is three. If this turtle didn't goįorward, down, and up, what did this turtle do? We'll start at t equals zero. So let's just read this graph and figure out what this So somewhere at like two and four seconds this turtle was at two meters. What that means is if you find the turtle at some point over here at x equals two, then the graph should represent that the turtle is at x equals two by showing the value is two. In this case I wrote is as x, so this is gonna be And I'm doing that because look over here we're graphing. So I'm gonna label this x and it's gonna be measured in meters. Graph actually says let me lay down a horizontal access here. So maybe the turtle went forwardĪnd then down and then up, but that's not right. The first mistake a lot of people make is they think that well maybe the shape of this graph is the same as the shape the And this graph represents the motion of this particular turtle. And I don't want a sternly worded letter. And instead of just saying object, let's make it specific. To write an equation or say a bunch of words. Basically specify theĮntire motion of the object, and you didn't even have Why do so many people love these things? Because you could compactĪ ton of information about the motion of an object into the small little space right here.
